I have added an Add-On for Postgresql.
I am connecting to the database like this :
services.AddDbContext<DataContext>(optionsBuilder =>
optionsBuilder.UseNpgsql(Configuration.GetConnectionString("PostgresSqlDatabaseConnection")));
My Connection String
"PostgresSqlDatabaseConnection": "User ID=ddojar225ki3s4;Password=correct_password;Server=ec2-34-242-89-204.eu-west-1.compute.amazonaws.com;Port=5432;Database=ddojar225ki3s4;Integrated Security=true; Pooling=true"
Solution
I had to add
SSL Mode=Require; to the connection string.
Be careful NOT to type Required or SSL Mode=SSL.Require

I was able to successfully integrate the elastic search sink in my .net app, now I am trying to setup the FailureCallback option but every time there is an error the exception in LogEvent is null, I can see the actual error in the console but I want to be able to capture this exception in my failure callback function, here is my current configuration:
myLogger = new LoggerConfiguration()
.WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(elasticSearchUrl))
{
AutoRegisterTemplate = true,
AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv6,
IndexDecider = (#event, dateTimeOffset) =>
{
//some logic here
return $"custom-index";
},
EmitEventFailure = EmitEventFailureHandling.WriteToSelfLog | EmitEventFailureHandling.RaiseCallback,
FailureCallback = HandleElasticError
})
.Enrich.WithProperty("Environment", Config.Environment)
.Destructure.ByTransforming<ExpandoObject>(JsonConvert.SerializeObject)
.CreateLogger();
Here is my HandleElasticError function:
private void HandleElasticError(LogEvent e)
{
FileLogger.Error(e.Exception, e.MessageTemplate.Text, e.Properties);
}
When I attach the debugger and inspect the LogEvent, exception is null, however in the output window in Visual Studio I can see the actual error:
2020-11-30T20:55:07.7820674Z Caught exception while preforming bulk operation to Elasticsearch: Elasticsearch.Net.ElasticsearchClientException: The underlying connection was closed: An unexpected error occurred on a send..

I am not concerned about the error, I know what the issue is, I just want to be able to capture this exception in my failure callback function.
Any ideas?
LogEvent.Exception is the Exception shipped with your call to (for example) logger.Error(myException) - not the exception thrown by failure to write to Elastic Search.
The exception you're trying to catch doesn't look to be exposed by the sink as it just passes the LogEvent to FailureCallback and not exception that caused the failure.
Here's what it could look like were the exception exposed.
you can use:
StreamWriter writer = File.CreateText(...);
Serilog.Debugging.SelfLog.Enable(writer);
I am trying to make Rebus work on Oracle DB but I keep getting errors.
I have the following configuration in my Startup:
In the ConfigureServices
services.AutoRegisterHandlersFromAssemblyOf<NewActionRequestMessageHandler>();
services.AddRebus(configure => configure
.Logging(l => l.Serilog())
.Transport(t => t.UseOracle(connectionString, "QueueTable", "Queue"))
.Routing(r => r.TypeBased()
.Map<NewActionRequestMessage>("Queue")
.Map<RevokeActionRequestMessage>("Queue"))
.Subscriptions(s => s.StoreInOracle(connectionString, "Subscriptions")));
In the Configure
var bus = app.ApplicationServices.GetRequiredService<IBus>();
app.ApplicationServices.UseRebus();
bus.Send(new NewActionRequestMessage());
The error I get is:

Help?
I am testing an Xamarin.iOS Application on a real device (iPhone 6s with iOS 12.1) with Xamarin.UITest.
When I am running my few UI Tests, the first test always seam to crash (regardless of what is happening inside the test) due to the same error (see below).
Enviroment is:
Xamarin.UITest 2.2.7
NUnitTestAdapter 2.1.1
NUnit 2.6.3
Xamarin.TestCloud.Agent 0.21.7
Setup is:
[SetUp]
public void Setup(){
this.app = ConfigureApp.iOS
.EnableLocalScreenshots()
.InstalledApp("my.app.bundle")
.DeviceIdentifier("My-iPhone6s-UDID-With-iOS12.1")
.StartApp();
}
[Test]
public void FirstTestThatCouldBeEmpty(){
//But doesn't have to be empty to produce the error
}
Resulting error:

Sometimes it is this error:

System.Net.WebException : Unable to read data from the transport connection: Connection reset by peer.
System.IO.IOException : Unable to read data from the transport connection: Connection reset by peer.

What could be a solution to this?
Doing the version puzzle of the nuget packages got me this far, that all tests are working besides this one.
A dummy test would be a possibility, but that would that countinous builds with those test would never be in the state of "successful" because this one test that is failing =(
I was able to find a work around for this issue, and really any issue with the device agent not connecting to the app under test.
public static IApp StartApp(Platform platform)
{
if (platform == Platform.iOS)
{
try
{
return ConfigureApp.iOS
.InstalledApp("com.example")
#if DEBUG
.Debug()
#endif
.StartApp();
}
catch
{
return ConfigureApp.iOS
.InstalledApp("com.example")
#if DEBUG
.Debug()
#endif
.ConnectToApp();
}
}
In plain language : "If you tried to start the app, and something went wrong, try to see if the app under test was started anyway and connect to it"
Note : As https://stackoverflow.com/users/1214857/iupchris10 mentioned in the comments, a caveat to this approach is that when you run tests consecutively, while the StartApp call will in theory reliably shut down the app, with the point of failure being reconnection, if it does not and you are running tests consecutively, you will simply connect to the running app instance in whatever state it was left in. This approach offers no recourse. Xamarin's StartApp will throw Exception, rather than a typed exception, and so mitigating this will rely on you parsing InnerException.Message and keeping a table of expected failures.

I have the below code to SFTP to a location
public static void putFile(String username, String host, String password, String remotefile, String localfile){
JSch jsch = new JSch();
Session session = null;
try {
session = jsch.getSession(username, host, 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword(password);
session.connect();
Channel channel = session.openChannel("sftp");
channel.connect();
ChannelSftp sftpChannel = (ChannelSftp) channel;
sftpChannel.put(localfile, remotefile);
sftpChannel.exit();
session.disconnect();
} catch (JSchException e) {
e.printStackTrace();
} catch (SftpException e) {
e.printStackTrace();
}
}
I am able to SFTP the document from my local machine using the above code. However when I am trying from a different environment to SFTP to the same location I am getting the follow error.
com.jcraft.jsch.JSchException: invalid server's version string at
com.jcraft.jsch.Session.connect(Session.java:253)
Note : I am using jsch-0.1.31.jar file.
on printing out session.getClientVersion() I am getting "SSH-2.0-JSCH-0.1.31".
I tried to upgrade the jar file to jsch-0.1.51.jar then session.getClientVersion() = "SSH-1.5-JSCH-0.1.51" and I am getting the following error
com.jcraft.jsch.JSchException: Session.connect: java.net.SocketException: Connection reset at com.jcraft.jsch.Session.connect(Session.java:558)
Please can you help me on what parameters should I be looking into and what is causing it to run from my local machine and upload to the same SFTP location and not from other environment?
As noted by #Kenster, the exception is about server's version string, not client's. The "invalid server's version string" exception is thrown by following code in Session.connect:
if(i==buf.buffer.length ||
i<7 || // SSH-1.99 or SSH-2.0
(buf.buffer[4]=='1' && buf.buffer[6]!='9') // SSH-1.5
){
throw new JSchException("invalid server's version string");
}
First, I would try to connect with some client that logs the version string and see yourself. For example with WinSCP, search its log for a pattern like:
. 2014-09-03 17:01:20.596 Server version: SSH-2.0-OpenSSH_5.3
(I'm the author of WinSCP)
Though possibly it's not about version string at all. I would rather believe the error raised by the new version, the Connection reset. The old version may fail to detect that the connection was aborted prematurely and tries to validate some random or incomplete data.
The Connection reset may indicate wide variety of different errors
Server refusing a connection from the other location
Some firewall or proxy not allowing the connection to pass through
